User Reviews

I absolutely love using the nest watch app! It’s intuitive and well designed so that it makes it easy to track nesting birds anywhere I go. Logging data is straightforward and detailed. You can log everything from nest materials to the number of eggs and hatchlings, which makes the observations really meaningful and accurate. Another thing I love is the ability to upload photos. It’s super cool to look back and see the progress of birds as they grow up. I’ve learned a lot about local species and their nesting behaviors through the app. Highly recommend to anyone who enjoys birding and wants to contribute to real scientific research. The Cornell Lab of Ornithology has done a great job with making an app that’s super fun and easy to use!
